This Affects:
spring-cloud-config-serverTL;DR
spring-cloud-config-server does not validate webhook requests to the /monitor endpoint. An authenticated high-privilege caller can send crafted monitor payloads that exhaust server resources. This can make configuration refresh unavailable to other clients. The patch validates webhook requests before they are processed.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the Config Server /monitor webhook endpoint is exposed.
Background info
spring-cloud-config-server is vulnerable to Denial of Service (DoS) in versions 0.0.1 - 5.0.4.
How to fix this
Upgrade the org.springframework.cloud:spring-cloud-config-server library to the patch version.
